The LFC (or LCG File Catalog) has been developed by LCG to resolve problems with the EDG Replica Manager File Catalog.

Tier 2s need to install a local version of the LFC catalog, as set out in Tier 2 DM Requirements. Why is this necessary? This site-local catalog fits into some of the VOs data processing models and provides adds new generic middleware service to LCG .


It's easiest to install the LFC on a single box using YAIM, but you can share the LFC with other LCG components as well.
